GB/T 2441.3-2010 《Determination of urea - Part 3: Water content - Karl Fischer method》 Related products
This standard is applicable to the determination of moisture content in urea synthesized from ammonia and carbon dioxide. The Karl Fischer method is used as the main determination method. The Karl Fischer reagent containing pyridine is required for arbitration. The standard specifies the principle of determination, the required reagents and equipment, and detailed operation steps. The content of the test material is determined by quantifying the moisture in the reaction sample. This standard provides a reliable technical basis for the accurate determination of urea moisture.
